PRESS;

Original application filed November is, 1925, Serial No. 69392. Dividedand this application filed m llfy invention relates to presses and inparticular to a press for the baling of paper or other finely dividedand fragmentary nfat'eri'al, and is a'divis'ion of my applicaii It isthe objectiof my invention to pri'nide a press'of this character whichwill" g dly bale-the maeri'al in question, which may be readilyassembled and which will have suit able safety devices to insurecontinuous operfactured; but which will have requirements of strengt'l'iease of replacement not heretofore obtainable.

In the accompan ing drawings Figure l is a side elevation oftlie'coi'npl'ete' press with the feeding board in its elevatedposition;-

Figure 2 is section on the line 6--6"of Figure 1, showing thearrangement of the lower bearings of the lower stud=shafts and gears,together with a section showing the construction of the plunger head.

Figure 3 is a section showing the arrangement of the wearing plates andof the plunger head. 7

Referring to the drawings in detail. 1 is a base or platform on which ismounted the press. A lurality of transverse I-bcams, 2, 3. 4 and 5,arranged transversely on this platform for the purpose of supporting thebottom plate 6. Side rails 11 and 12 of the plate 6 are provided on thissupport, longitudinally, upon which members 11 and 12 are the angleirons or rails 13 and 14*. which are supported and bolted by the bolts15. To these lower rails 13 and 14 are bolted by the bolts 16 the sideplates 1'? and 18. These side plates extend upwardly within and aboveupper rails 19 and 20 which are bolted thereto by the bolts 21. Theseside plates are tapped at their upper end by a plate 22. 2-3 designatesa driving pulley which is driven by a belt from any erial Ne. mass-c1suitable source of power. This pulley is mounted upon the driving shaft24 which carries the" driving" pinion 25 which" drives a driven gear25o'fi fih amen; shaft 24 Ontliis' daiviag sliiift B a're a pair of spacedp'iuio'ns which en age with their respective gears 3s.

These plates 58 are provided with outwardly extending flanges 59 at thetop and l'iOil-OU]. The bottom flanges are provided with side guideplat-es 60 which are bolted to the flange 59 by the bolts 61 which alsoretains the inverted U-shaped jaw 62 for supporting the roller 63 whichrolls upon. the bottom plate 6. The U-shaped member 62 is provided withshoulders 64 which fit on either side of the flange 59. The top flange59 has supported thereon a top plate for the plunger 65, which engageswith the wearing plates 66. These Wearing plates are preferably of woodand are suspended by the bolts 67 from the cap plate 68.

The end of the plunger head is formed by a steel plate 69 connected tothe vertical side plates 58 by internally disposed angle irons 70 boltedto the plate 69 in the plate 58 by the bolts 71. This provides a lightweight out extremely strong assemb y a disassembly structure. It is amatter of great advantage to have a built-up structure of this characterwith a steel built plunger head.

In the eventor" wear, due to the thrust of the plunger upwardly againstthe top of the machine, the wearing blocks of wood can be taken away andnew ones replaced. T he bottom of the plunger is carried on rails sothat the friction at that point is thus taken care or".

It will be also understood that I desire to comprehend within myinvention such modifications as may be necessary to adapt it to varyingconditions and uses.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is:

1. In a baler, a guide portion for the reciprocating compressionplunger, a reciprocating compression plunger, a plurality of wearingplates detachably interposed between the top of said plunger and theinside oithe top of the baler.

2. In a baler, a guide portion for the reciprocating compressionplunger, a recipro eating compression plunger, a plurality of wearingplates interposed between the top of said plunger and the inside of thetop of the baler.

3. In a baler, a guide portion for the reciprocating compressionplunger, a reciprocating compression plunger, a plurality of wearingplates detachably interposed between the top of said plunger and theinside of the top of the baler, and a plurality of rails interposedbetween the bottom of said plunger and the inside of the bottom of saidbaler for supporting the plunger.

4. In a baler, a compression plunger for compressing the material in thebaler consisting of a compression head plate, supportin members attachedthereto and to vertica 1y disposed right angle thrust plates, and

means for connecting the pitman to said thrust plates.

5. In a baler, a compression plunger for compressing the material in thebaler consisting of a compression head plate, supporting membersattached thereto and to vertica y disposed right angle thrust plates,and in ms or connecting the pitman to said thrust plates, said headplate being composed of a separable sheet of metal.

6. In a baler, a compression plunger for compressing the material in thebaler consisting of a compression head plate, supporting membersattached thereto and to vertically disposed right angle thrust plates,and means for connecting the pitman to said thrust plates, said headplate being com posed of a separable sheet of metal, and means fordetachably connecting said head plate and thrust plates by internallydisposed vertical angular memhers associated with the junction points ofsaid thrust plates and said head plates.

7. In a compression plunger in a. baler, a bed plate, vertical thrustplates, a cap plate, and a head plate, means of attaching said headplate and said thrust plates and a pitman mounted on said thrust platestherebetween.

8. In a compression plunger in a baler, a bed plate, vertical thrustplates, a cap plate, and a head plate, means of attaching said headplate and said thrust plates, and a pitman mounted on said thrust platestherebetween, means for supporting said base plate on rollers Within thebaler and means adapted to Wear at a greater rate than the top plate ofthe plunger carried on the inside of the baler adjacent thereto to takethe up ward thrust and wear of the compression plunger.

In testimony whereof I afiix my signature.

BRUCE ROLLMAN.
